Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The resource scheduling method provided by the present application can be applied to the application environment shown in fig. 1, where the base station 100 is in communication connection with the terminal device 200. The terminal 200 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, portable wearable devices, and the like. The base Station may be, but not limited to, a macro base Station, a micro base Station, a small base Station, and other types of base Station devices, and may be a base Station (BTS) in Global System for Mobile communication (GSM) or Code Division Multiple Access (CDMA), a base Station (NodeB, NB) in Wideband Code Division Multiple Access (WCDMA), an evolved Node B (eNB, eNodeB) in LTE, a relay Station, an Access point, a base Station in a future 5G network, a Customer Premise Equipment (CPE), and the like, and is not limited herein.
In an embodiment, as shown in fig. 2, a resource control method is provided, which is described by taking the application of the method to the base station in fig. 1 as an example, and includes:
s101, acquiring distribution characteristics of each resource fragment in a resource pool of a channel; the distribution characteristics include the size of each resource fragment.
The channel may be an uplink shared channel or an uplink control channel, and the type of the channel is not limited herein.
The resource fragmentation is generated in the process of continuously allocating and releasing the resource in the resource pool, for example, the base station allocates the resource a to one user equipment in the resource pool, after the user equipment completes data transmission, the base station releases the resource a, and allocates the resource to another user equipment in subsequent scheduling, and the size of the resource required by the another user equipment is smaller than that of the resource a, so that fragmentation is generated at the resource position. Along with the continuous scheduling of resources in the resource pool, the increase of resource fragments reduces the resource utilization rate.
The distribution characteristic may be a size of each resource fragment in a resource pool of the channel, may also include a position of each resource fragment, and may also include a frequency domain bandwidth corresponding to each resource fragment, a time slot size in a time domain, and the like, and a specific type of the distribution characteristic is not limited herein.
When the base station obtains the distribution characteristics of the resource fragments, the base station can obtain the positions of the resources which are not scheduled according to the resource scheduling result, then further determine whether the resources at the positions of the resources are the resource fragments, and determine the sizes and the positions of the resource fragments; in addition, the base station may also search the resource pool for the resource fragments according to the frequency domain order or the time domain order, and further obtain the distribution characteristics such as the size of the resource fragments, and the manner of obtaining the distribution characteristics is not limited herein.
S102, determining occupied resources of the distributed users in the edge area of the resource pool.
The edge region refers to a resource region adjacent to a resource pool of another channel in the resource pool of the channel. The range of the edge area may be an area range that the base station may divide from the boundary of the resource pool according to a preset size; the range of the edge area is determined according to the number of resource fragments, and the specific range of the edge area is not limited herein.
The allocated user refers to a device for which the current base station has allocated resources, and may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, portable wearable devices, and the like.
The allocated user in the edge area may be one user equipment in the edge area, or multiple user equipments, or may be all user equipments in the edge area, which is not limited herein.
When determining the occupied resources of the allocated users, the base station may determine which resources are scheduled resources in the edge region according to the resource scheduling result, and may also perform search in the edge region, where the determination manner of the occupied resources is not limited herein.
S103, determining target resource fragments matched with the occupied resources in the resource fragments according to the distribution characteristics.
On the basis of the above steps, the base station may match the resource fragments with the occupied resources according to the distribution characteristics, and determine the target resource fragments corresponding to the occupied resources.
Specifically, the base station may obtain occupied resources matching the size of the resource fragments according to the size sequence of the resource fragments, and determine the resource fragments as target resource fragments occupying the resources; in addition, the base station may also obtain a target resource fragment matching the size of the occupied resource according to the position arrangement order of the occupied resource, and the determination method is not limited herein.
S104, adjusting the occupied resources of the allocated users to the positions of the target resource fragments, and releasing the occupied resources in the resource pool.
After determining the target resource fragments matched with the occupied resources, the base station can adjust the occupied resources of the allocated users to the positions of the target resource fragments, so that the target resource fragments can be filled and used; further, the base station releases the occupied resources in the resource pool, so that the occupied resources can be converted into idle resources, and can be scheduled again.
Specifically, when releasing the occupied resources, the base station may adjust the occupied resources to idle resources, or may adjust the occupied resources to resource pools of other channels, which is not limited herein.
Optionally, the edge area is an area adjacent to the traffic channel in the resource pool, and when the base station releases occupied resources in the resource pool, the base station may adjust the occupied resources to the resource pool of the traffic channel, so as to improve available resources in the traffic channel, and improve cell capacity and traffic throughput.
In the resource control method, the base station acquires the distribution characteristics of each resource fragment in the resource pool of the channel; wherein the distribution characteristics comprise the size of each resource fragment; then, determining occupied resources of the distributed users in the edge region of the resource pool; determining target resource fragments matched with occupied resources in all the resource fragments according to the distribution characteristics; and finally, adjusting the occupied resources of the allocated users to the positions of the target resource fragments, and releasing the occupied resources in the resource pool. The base station acquires the distribution characteristics of the resource fragments, so that the base station can determine the target resource fragiles matched with the occupied resources in the resource fragments according to the distribution characteristics, the occupied resources are adjusted to the positions of the target resource fragments, the resource fragments in the resource pool can be filled, and the resource utilization efficiency in the resource pool is improved; further, the base station can release the resources in the resource pool of the channel to other channels by releasing the occupied resources, thereby completing the integration of the wireless resources.
Fig. 3 is a flowchart of a resource control method in another embodiment, which relates to a specific manner in which a base station determines occupied resources of allocated users, and based on the above embodiment, as shown in fig. 3, the step S102 includes:
s201, starting from the boundary of the resource pool, acquiring an edge area matched with the sum of the sizes of the resource fragments.
Specifically, when determining the edge region, the base station may determine according to a sum of sizes of the resource fragments, so that the resource fragments may be filled by occupied resources in the edge region, so that the resource fragments may be filled as much as possible. The base station may determine an area matching the size of the sum as an edge area from the boundary of the resource pool.
S202, acquiring an occupied resource set composed of occupied resources of all allocated users in the edge area.
Further, the base station may acquire occupied resources of all allocated users in the edge area. Specifically, the base station may determine whether resources in the resource pool are scheduled, determine resources occupied by the same allocated user as one occupied resource, and obtain occupied resources of all allocated users according to the above process.
In the occupied resource set acquired by the base station, each occupied resource may be sorted according to the distance between the resource and the boundary of the resource pool, or sorted according to the size of the occupied resource, which is not limited herein.
According to the resource control method, the base station determines the edge area according to the sum of the sizes of the resource fragments, so that the resource fragments can be filled through occupied resources in the edge area, the resource fragments can be filled as far as possible, and the utilization rate of the resources is effectively improved.
Fig. 4 is a flowchart of a resource control method in another embodiment, which relates to a specific manner for a base station to determine a target resource fragment, and based on the foregoing embodiment, as shown in fig. 4, the foregoing S103 includes:
s301, sequencing all occupied resources in the occupied resource set according to the distance between each occupied resource and the boundary.
Specifically, the base station may rank the occupied resources in the occupied resource set according to the distance between the occupied resources and the boundary. For example, as shown in fig. 5, the base station may number each occupied resource from a boundary position of the resource pool to obtain an occupied resource set composed of 15 occupied resources shown in fig. 5, where a smaller number indicates that the occupied resource is closer to the boundary; further, the base station may register the size of each occupied resource.
S302, according to the sequence of the distance from near to far, target resource fragments matched with the size of occupied resources are determined in sequence in the resource fragments.
Further, the base station may determine, in order from near to far, target resource fragments matched with the size of the occupied resources in the resource fragments according to the distance between the occupied resources and the boundary. Because the boundary of the resource pool is fixed, after determining the target resource fragment corresponding to the occupied resource close to the boundary, the base station can gradually release the occupied resource near the boundary in the process of resource control, thereby completing the adjustment of the boundary of the resource pool, and ensuring that the resource in the resource pool can be adjusted to the resource of other channels.
Specifically, when determining a target resource fragment occupying a resource, the base station may determine whether an alternative resource fragment larger than or equal to the occupied resource exists in each resource fragment; and if so, determining the target resource fragment according to the alternative resource fragments.
When determining the target resource fragment according to the candidate resource fragments, the base station may randomly select one resource fragment from the candidate resource fragments to determine the resource fragment as the target resource fragment, or may determine the obtained first candidate resource fragment as the target resource fragment, which is not limited herein.
Optionally, the base station may determine whether the alternative resource fragments are unique; if yes, determining the alternative resource fragments as target resource fragments; if not, determining the resource fragment with the minimum size in the alternative resource fragments as the target resource fragment.
According to the resource control method, the base station determines the target resource fragments matched with the sizes of the occupied resources in the resource fragments in sequence according to the distance between the occupied resources and the boundary, and can release the occupied resources near the boundary to complete the adjustment of the boundary of the resource pool, so that the resources in the resource pool can be adjusted to the resources of other channels.
In an embodiment, after determining that there is no alternative resource fragment larger than or equal to the occupied resource in each resource fragment, the base station may schedule a resource for the allocated user in an idle resource in the resource pool that is farthest from the boundary of the resource pool.
Specifically, when the occupied resources of the allocated users do not have the alternative resource fragments, the base station may mark the allocated users as secondary allocation users; after matching of occupied resources and resource fragments is completed, scheduling resources for secondary allocation users in idle resources which are farthest away from the boundary in a resource pool; and completing matching of occupied resources and the resource fragments to represent that each resource fragment in the resource pool is filled, or not having the resource fragment matched with the occupied resources in each resource fragment.
Further, if the secondary allocation users are multiple user equipments, the base station may sequentially schedule resources for each secondary allocation user according to a distance between an occupied resource corresponding to each secondary allocation user and a resource boundary.
Continuing to take the resource pool in fig. 5 as an example, the base station may sequentially determine the target resource fragments corresponding to each occupied resource numbered 1-15, obtain the target resource fragments corresponding to other occupied resources except the number 10 occupied resource, and complete the matching between the occupied resources and the resource fragments; then, the base station may respectively correspond the respective resource fragments to the respective numbers, as shown in fig. 6, so that the resource fragments in the resource pool may be filled. Furthermore, the base station can adjust the successfully matched occupied resources to the positions of the corresponding target resource fragments, and release the occupied resources in the resource pool, so that the resource positions where the original occupied resources are located are free; then, the base station may adjust the number 10 occupied resource which is not successfully matched to the idle resource which is farthest from the boundary.
According to the resource control method, when the alternative resource fragments matched with the occupied resources do not exist in the resource fragments, the base station schedules resources for the allocated users in the idle resources which are farthest away from the boundary of the resource pool in the resource pool, so that the size of the idle resource region at the boundary of the resource pool can be larger, more resources are released, and the resource utilization efficiency is improved.
It should be understood that although the various steps in the flow charts of fig. 2-4 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
